系统仿真是风险评价的一种重要手段,针对商业银行IT操作风险预警问题,提出了一种基于稀有事件仿真的IT操作风险评估方法。采用商业银行IT操作风险的概率作为衡量IT操作风险高低的标准,构造基于稀有事件的商业银行IT操作风险识别模型,利用交叉熵方法构建了一种稀有事件仿真的有效算法,并由此估计出发生损失的概率。实证分析结果表明,模型对商业银行IT操作风险具有很强的识别能力,从而提供了一个风险预警的新视角。  相似文献

IT治理的提出,为企业在实现业务目标的同时平衡IT投资和风险方面提供一种机制。为了确保企业能够实现业务目标,实现在风险管理和收益实现间的有效平衡,指导和管理各类IT活动就显得非常迫切。国际信息系统审计与控制协会提出了“信息系统和技术控制目标”(COBIT)。作为IT治理的核心模型,COBIT包含34个信息技术过程控制,并归集为四个控制域:IT规划和组强(Planning and Organization)、系统获得和实施(Acquisition and Implementation)、交付与支持(Delivery and Support)以及信息系统运行性能监控(Monitoring)。在本次系列讲座中,我们将对每一个控制域(Control domains)内的过程控制有选择的展开论述。  相似文献

Information technology (IT) platform migration incurs a great deal of risk because of the massive rewriting of legacy systems and a wide range of new technology adoptions. Therefore IT platform decisions need to be made in a mindful manner because of the high degree of investment risk. However, more aggressive migrations, compared to the global trend, to an open system have been observed in Korean organizations. This phenomenon defies the common understanding of IT investment risk and encourages the investigation of the elusive characteristics underlying IT investment decisions. The effect of IT decision-makers’ perceptions and risk propensity on their IT platform migration decisions is examined in the context of risky decisions. In addition to risk perception, decision-makers’ risk propensity also has a significant effect on IT investment decisions. By observing the monarchical IT governance and IT-biased careers of decision-makers, some implications of large-scale IT investment decisions are derived.  相似文献

The postmortem examination of failed IT projects reveals that long before the failure there were significant symptoms or “early warning signs.” This article describes the top 12 people-related and project-related IT project risks, based on “early warning sign” data collected from a panel of 19 experts and a survey of 55 IT project managers.  相似文献

The success rate for information technology (IT) projects continues to be low. With an increasing number of IT projects in developing countries such as China, it is important to understand the risks they are experiencing on IT projects. To date, there has been little research documenting Asian perceptions of IT project risk. In this research, we examine the risks identified by Chinese senior executives (SEs) and project managers (PMs), and compare these two groups. The importance of top management support in IT projects is well documented. Prior research has shown that from the perspective of IT PMs, lack of support from SEs is the number one risk in IT projects. Surprisingly, senior executives' perceptions towards IT project risk have never been systematically examined. One reason why lack of support from senior executives continues to represent a major risk may be that senior executives themselves do not realize the critical role that they can play in helping to deliver successful projects. In this study, we use the Delphi method to compare the risk perceptions of senior executives and project managers. By comparing risk factors selected by each group, zones of concordance and discordance are identified. In terms of perceived importance ascribed to risk factors, PMs tend to focus on lower‐level risks with particular emphasis on risks associated with requirements and user involvement, whereas SEs tend to focus on higher‐level risks such as those risks involving politics, organization structure, process, and culture. Finally, approaches for dealing with risk factors that are seen as important by both SEs and PMs are provided.  相似文献

Decisions to invest in information technology (IT) infrastructure are often made based on an assessment of its immediate value to the organization. However, an important source of value comes from the fact that such technologies have the potential to be leveraged in the development of future applications. From a real options perspective, IT infrastructure investments create growth options that can be exercised if and when an organization decides to develop systems to provide new or enhanced IT capabilities. We present an analytical model based on real options that shows the process by which this potential is converted into business value, and discuss middleware as an example technology in this context. We derive managerial implications for the evaluation of IT infrastructure investments, and the main findings are: (1) the flexibility provided by IT infrastructure investment is more valuable when uncertainty is higher; (2) the cost advantage that IT infrastructure investment brings about is amplified by demand volatility for IT-supported products and services; (3) in duopoly competition, the value of IT infrastructure flexibility increases with the level of product or service substitutability; and (4) when demand volatility is high, inter-firm competition has a lower impact on the value of IT infrastructure.  相似文献

The importance of IT has been increasing in both developing and developed countries over the past three decades. However, almost all findings on IT productivity have been based on data collected in developed countries, while research on productivity in developing countries has been sparse. We studied the effect of IT investment on firm-level productivity in the Chinese electronics industry using a production function model. We found that the direction and size of the impact of IT investment on productivity in China were generally similar to results of studies for the United States and concluded that Chinese firms should invest more in IT. Finally, contrary to popular belief, labor is still an important factor in the production function of the Chinese electronics industry, despite its status as a high-technology industry.  相似文献
